KUMAMOTO, 11 Oct - Flanker Josh Navidi is confident the World Cup is still to see the best of Wales as they eye a quarter-final clash with France.
"There is a lot more still to come. We're working to put little things right each week and we need to keep moving forward and improving throughout the tournament," said Navidi, pictured above left with scrum-half Gareth Davies.
Wales maintained their perfect record in Pool D with a hard-fought 29-17 victory over Fiji at Oita Stadium on Wednesday after trailing 10-0.
"We knew what type of game Fiji were going to play, and fair play to them they brought it. They executed it well.
"They are a big bunch of boys. We did deal with them at times in the second-half, but in the first they played well. They were on fire to be fair to them.
"They've got the best offloading game out there, hands down. It was their last game and they came out firing.
"Our discipline let us down at times and we didn't shut down their offloading game early on. In the second half we did stop it, but we need to take those lessons and move forward to Uruguay now."
Even two points against Uruguay at Kumamoto would be enough for Wales to seal top spot and book a quarter-final in Oita on 20 October against France who will finish runner-up in Pool C after their game with England was cancelled.
"We want to get the top seed," said Navidi. "Then we can concentrate on the quarter-finals and move forward from there. It's knockout stages and that's been our mindset from the start – taking it game by game."
Wales beat England and France on their way to a Six Nations Grand Slam this year. They also defeated England when the teams met in a warm-up game in Cardiff having lost at Twickenham.
"You could say it gives us a psychological advantage, but this is a World Cup so it's a different ball game. We'll look forward to it, but it's Uruguay first."
Coach Warren Gatland will field a much-changed team against Uruguay on Sunday to give some of his walking wounded more chance to recover. Outside-half Dan Biggar will not be considered due to a head injury.
Biggar is ruled out after his collision with team-mate Liam Williams and is facing return-to-play protocols before the quarter-final. So Rhys Patchell, the only other fly-half in the Wales squad, is set to start against Uruguay.
Full-backs Williams or Leigh Halfpenny, centre Hadleigh Parkes and winger Hallam Amos, who has yet to play in the tournament, are all contenders to act as stand-in fly-half.
